Launched two years ago, Jenner's cosmetics line has been a massive success, selling more than $630 million in product and bringing the company's worth to a cool $800 million, with the reality star owning 100 per cent.

"It’s incredible to be recognized for something I’m so passionate about, and I’m really grateful for that," said Jenner, who is also on Forbes' cover. "I’ve always loved makeup and worked really hard to bring the first lip kit to market. Connecting with my fans and creating product that excites them has been an incredible process. I’ve learned so much along the way and I hope to inspire others to follow their dreams."

Jenner's half-sister Kim Kardashian also made the list down at No. 54 with an estimated net worth of $350 million, thanks in part to her own successful makeup line KKW Beauty.

Following behind were Little Caesars co-founder Marian Ilitch with $4.3 billion, Epic Systems founder and CEO Judy Faulkner with $3.5 billion and in fourth place, former president and CEO of HP Meg Whitman at $3.3 billion.

Other big names include Oprah Winfrey, #6 with $3.1 billion, Facebook COO Sheryl Sandberg at #12 with $1.6 billion, Madonna at #36 with $590 million, Barbra Streisand at #48 with $400 million, Beyonce at #53 with $355 million and Taylor Swift at #60 with $320 million.
